The attack on my forces has been very spirited from early
this morning. The appearance of fresh troops on the field now would have a
powerful effect, both by inspiring our men and disheartening the enemy. If you
will get upon the field, leaving all your baggage on the east bank of the
river, it will be a move to our advantage, and possibly save the day to us. The
rebel forces are estimated at over 100,000 men. My headquarters will be in the
log building on the top of the hill, where you will be furnished a staff
officer to guide you to your place on the field.

U.S. GRANT,

Major-General, Commanding.
